Two Interlinked Meters

Triggering changes in meter values

m1.amountusedvar.trace("w", my_upd1) # Trigger on change of value
m2.amountusedvar.trace("w", my_upd2)

Functions to update

def my_upd1(*args): # When Meter1 is updated
    m2["amountused"] = m1["amountused"] # m2 is updated

def my_upd2(*args): # When Meter2 is updated
    m1["amountused"] = m2["amountused"] # m1 is updated

import ttkbootstrap as ttk
from ttkbootstrap.constants import *

my_w = ttk.Window()
my_w.geometry("500x250")

def my_upd1(*args): # When Meter1 is updated
    m2["amountused"] = m1["amountused"]

def my_upd2(*args): # When Meter2 is updated
    m1["amountused"] = m2["amountused"]

m1 = ttk.Meter(
    my_w,
    amountused=25,
    metersize=225,
    meterthickness=30,
    interactive=True,
)
m1.grid(row=0, column=0, padx=10, pady=10)

m2 = ttk.Meter(
    my_w,
    amountused=25,
    metersize=225,
    meterthickness=30,
    interactive=True,
    bootstyle=SUCCESS
)
m2.grid(row=0, column=1, padx=10, pady=10)

m1.amountusedvar.trace("w", my_upd1) # Trigger on change of value
m2.amountusedvar.trace("w", my_upd2)

my_w.mainloop()
